Answer:
Collision theory states that the substance will have higher rate of reaction as the particles collide more frequently. In the case of lamp sugar, it quite intact and it would be best in hot cup since the increasing of temperature increases the kinetic energy of the lamp sugar making it dissolve faster as the particle increases its collision.
Granulated sugar are somehow have smaller size particle compared with lamp sugar. Granulated sugar will definitely dissolves faster in hot cup compared with lamp sugar but granulated sugar will dissolve faster also in ice tea compared with lamp sugar. Even if the particle are slowly colliding with other but since it is granulated it will still dissolve in ice tea.
